The present invention relates to a sander for automobiles, and has forits primary object to provide, in a manner as hereinafter set forth, adevice of this character embodying the novel construction, combinationand arrangement of parts through the medium of which traction of therear wheels of the vehicle will be materially increased when desired, ason slippery surfaces and skidding will be substantially eliminated.

Another important object of the invention is to provide a sander forautomobiles embodying novel control means through the medium of whichthe sander ma be caused to I function simultaneously with t eapplication "of the brakes of the automobile or disconnected from thebrake operating mechanism to permit the independent operation of saidmechanism and to permit the sanding mechanism to be brought into use byhand when necessary or desirable.

Other objects of the invention are to rovide a sander for automobiles ofthe 0 aracter described which will be simple in construction, strong,durable, efiicient and reliable in use, inconspicuous and which maybeexpeditiously installed for operation on automobiles of conventionalconstruction without the necessity of materially altering saidautomobiles structurally.

Figure 7 1s a detail view in vertical longitudinal section through thebottom portion of one of the hop rs showing the control valve in closedposition thereon.

Referring now to the drawings iii detail, it will be seen that thereference numeral 1 designates the rear. portion of the frame of anautomobile and 2 are the rear wheels thereof. A metallic supporting late3 extends across a rear portion of the fi ame 1 and rests thereon and issecured by suitable means as at 4. Secured to the plate 3 and dependingtherefrom are the hoppers 5 which are transversely alined and w 1ch areprovided with clean out openin which are closed by the removable plates6. The cleanout openi for the hoppers 5 are designated by the re 'erencenumeral 7. The su porting plate 3 is provided with openings 9 or fillingthe hoppers 5 with san sai filling openings 9 bem closed by theremovable plates 10.

pending from the bottoms of the hoppers 5 are the discharge necks 11. YPlates 12 are rigidly secured in any suitable manner to the bottoms onthe hoppers 5 forwardly of the discharge neck 11 and said plates 12 areprovided with right anglilarly disposed apertured ears 13 between w 'cha pivot pin 14 extends. The reference numeral 15 desi nates a swmgingvalve which is pivotal y mounted on t e plate 12 for swingin movement ina vertical plane toward an away from the free ends of the dischargenecks 11 through the medium of the apertured ears 16 through which thepin 14 passes. A.

spring 17 is convoluted about the pin 14 between the ears 16 and is oeratively engaged with the valve 15 for yie dingly urging the sametoward its closed position.

Each valve 15 is provided with a pad 18 of suitable material, such asleather or rubber,

for engagement with the free end of the respective discharge neck 11,Secured to the lower sides of the valves 15 are the elongated loops 19the purpose of which will be present- 1y set forth.

' Substantially hopper shaped housings 20 are mounted on the bottoms ofthe hoppers 5 and enclose the valves 15. In their inner sides the housin20 are provided with cleanout openings w ich are closed by the removableplates 21. These last named openings also allow access to be had to thevalves when desired.

Conduits 22 are connected to the housings for receiving sand therefromand extendv outwardly and downwardly and terminate in the nozzles 23which are disposed for-- rotatably into the ousings 20 and terminate inthe crank arms 27 wh1ch project into the loops 19 and are operativelyconnected to the valves 15 thereby. The crank shafts 26 further includea substantially U-shaped intermediate portion constituting an arm 28. Arod 29 is connected, at one end, to the upper end of the arm 28 of thecrank shaft 26 through the medium of a coil. spring 30.

An operating cable 31 is connected at one end to the other end of therod 29 and is trained over the pulleys 32 which are mounted on thesteering column 33 of the vehicle. The cable 31 is connected to a handlever 34 which is mounted for swinging movement on the steering column33.

The reference numeral 35 desi ates the usual brake pedal of the vehicleto which is pivotally connected the brake rod 36. The rod'29 is disposedin substantiall spaced parallelism to the brake rod 36. C amps 37 arefixed on the brake rod 36 at spaced points and slidabl embrace the rod29. The rod- 29 is provided with an opening for the reception of aremovable pin 38 which when engaged by the forward ost clamp 37,connects the rod 29 with the bra e rod 36 for actuation in a forwarddirection thereby. The floor board 39 of the vehicle is provided with anopening 40 through which access may be had to the pin 38 forconveniently removing or inserting same.

A closure plate 41 is provided for the opening 40. If desired, the pin38 maybe connected to the floor board 39 by a cable or chain 42 toprevent loss of said pin.

In use, the valves 15 are normally maintained in closed position by thesprings 17. With the pin 38 in position in the'openings ned when thebrakes of the vehicle the crankarms 27 swing the valves 15 downwardlyagainst the tension of the springs 17 to permit the sand to fiow bygravity from the hoppers 5.

Of course, the rod 29 may be moved forwardly independently by handwithout moving the brake rod 36, the pin 38 simply moving forwardly fromthe forwardmost clamp 37 when it is desired to open the valves 15 byhand. When the pin 38 is removed, the clamp 37 will slide freely on therod 29 upon movement of the brake rod 36, thus reventing opening of thevalves 15 when it is not desired to discharge the sand upon the application of the vehicle brake, as -in good weather or on dry streets.

It is believed that the many advantages of a sander in accordance withthe present invention will be readily understood, and al though thepreferred embodiment of the invention is as illustrated and described,it is to be understood that changes in the details of construction andin the combination and arrangement of arts may be resorted to which willfall within the scope of the invention as claimed.
